For what it's worth, the attachments for the camera I bought screw on with fine-thread screws.  It requires 8+turns to get them all the way seated.  I think they're extremely unlikely to fall off inside the cylinder.  I've seen borescopes where the mirror attachment just slides on with spring clips, and agree that seems dubious.

At some point I might try finding a small, high quality tiny *glass* mirror and epoxying it onto the plastic mirror attachment for my scope.  For now, though, the 180 degree bend works well for looking at the valves.  Not sure how many times I'll be able to switch it back and forth to look at the piston and cylinder walls before the wires break from flexing, though.

ok.  I was picturing something that clipped on the end.

I have this one from amazon. It works fairly well and takes good pictures and video if you need it. I helped a buddy complete a SB on his piper PA28 and found corrosion in places that mirrors will only dream of finding. https://www.amazon.com/Endoscope-Depstech-Waterproof-Videoscope-Inspection/dp/B00UH01UE8/ref=sr_1_15?ie=UTF8&qid=1486673503&sr=8-15&keywords=Borescope

Funny part is how the chinglish instructions describe the higher resolutions available yet their app only allows me 640x480. That's a bummer. I initiated a return with Amazon. I don't have the time to deal with decoding the raw image broadcast etc. if it is indeed a 2MP CCD.

I haven't tried to determine why the saved images from the camera are only 640x480

Just finished downloading pictures from my phone to my computer and wanted to follow up on this.

I did find some pictures taken from the endoscope camera that were 1024x768.  While that is not 2 megapixels, it is higher than 640x480, and is in fact the highest resolution selectable waith the cheapie app the directions instruct you to download.  I now remember that at 1024x768 resolution, I wasn't able to see an entire valve at once (see attached photos below).  Switching to 640x480 effectively "zoomed out" such that the image showed the entire valve.

I know, I know... this doesn't make any sense.  The resolution of an image and the optical (or digital) zoom are independent variables.  But again, I think the cheapie app software is to blame.  My guess is it processes the raw data from the camera differently depending on the resolution you choose.  I would bet it's trying to be "smart" in a way that's exactly the opposite of smart.

In summary, I think what I bought is a pretty decent little endoscope camera, that presently suffers from being used with poor software.

That works pretty well...
